Abstract (en)

A fuel injector (1) provided with: an injection valve (7) comprising an injection nozzle (3); a mobile needle (17) for regulating the fuel flow through the injection valve (7) and ending with a shutting head (27), which engages a valve seat (18) of the injection valve (7), is arranged externally with respect to injection valve (7) and presents a predetermined sealing diameter; an actuator (6) for displacing the needle (17) between a closing position and an opening position of the injection valve (7); a closing spring (10) which tends to maintain the needle (17) in the closing position of the injection valve (7) pushing the shutting head (27) against the valve seat (18) itself in a sense contrary to the feeding sense of the fuel; and a supporting body (4) having a tubular shape and presenting a feeding channel (5) within which a needle (17) is arranged; the needle (17), at an opposite end of the shutting head (27), is coupled to a balancing channel (28), which is at ambient pressure.
